IMPROVEMENT IN HEATING-STOVES.

Specification forming part of Letters Patent No. 146,35 l, dated January 13, 1874; application filed December 10, 1873.

l stoves]7 which stoves consist, essentially, of

an upright cylindrical body or lire-chamber, surmounted with a hemispherical or domeshaped top having a central opening, through which the products of combustion escape; and the object of my improvement is to render such stove capable of radiating an increased amount of heat without adding to the consumption of fuel.

` I accomplish this result in the following manner: The dome-shaped top has ttedwithin it a hollow hemispherical reflector or bafdeplate, Whose location is such as to leave an annular passage or flue between it and the in.- terior of the stove top, and the products of combustion, after being deflected by said plate, must then ascend within said flue before escapin g through the smoke-pipe; but before escaping from the stove the products ofy com bustion are compelled to pass through apertures in the neck of the deilector, and, owing to the comparatively limited area of said openings, and its devious course therethrough, the current of smoke is somewhat retarded within the annular ue. By thus retardin g the products of combustion before they escape into the smoke-pipe, two important advantages ensue. In the first place, the smoke, being retained in contact with the highly-heated baffle-plate,

has all of its combustible matters thoroughly consumed. In the second place, the heat, being diverted by the baffle* plate, and not allowed to take a direct central route, is brought more intimately` in contact with the sides of the stove, and consequently more heat is radiated therefrom than would be done in case the baffle-plate were omitted.

Figure l is a representation of a stove provided with my improved4 deflector, the upper portion of said stove being in section, while the lower part thereof is shown in elevation.

Fitted concentrically within this dome-shaped top is a hollow hemispherical deector or baf-r fle-plate, E, whose location is such as to leave an annular ue, F, between it and the interiorof the stove top or cover. Cast with said deilector, and projecting upwardly therefrom, is a cylindrical neck, G, which is adapted to enter and fit snugly within the neck D of the stove top. The neck Gr is open at top, closed at bottom, and is pierced with a number of apertures, H, whose united area is somewhat less than the area of the annular ue F, in order that the products of combustion may be momentarily retarded before escaping into the smoke-pipe. It is preferred to secure the deector to the stove by means of rivets or staybolts I, which traverse tubes J, although'any other suitable retaining devices may be substituted for these bolts and tubes. K is the nre-door, L the ash-pan, and M a rock-shaft, which latter may operate any approved form of shaking grate.,

The operation of my stove will be readily understood by referring `to Fig. 1, in which it will be seen that the products of combustion cannot take a natural or directly-central passage from the fire-chamber B to the neck D r on account of the interposition of the baleplate E, which deflects the fire and smoke on all sides, and compels them to escape up the annular flue F. Owing to the limited area of apertures H, the products of combustion can- .i

not pass rapidly through the flue F, but they are detained therein long enough to belbrought intimately in contact with the highly-heated baffle-plate, which detention therewith causes a thorough consumption of theinflammable gases, &c. These gases being consumed directly under the top or cover C, the result is that an unusual amount of `heat is radiated from the stove. i

I claim as my invention- In combination with the stove top C, the In testimony of which invention I hereunto eorrespondingly- 'shapedV hollow defleetor or set my hand. bafIe-pIate E, annular ue F, and perforated tube or cylinder G H', which latter projects A upwardly from said deector and enters the Attest:
